Dead Air Silencers Xeno A1 Flash Hider .30 Caliber 1/2x28 Nitride Black. The Xeno Flash Hider gives you a lightweight suppressor mounting option with non-negotiable repeatability and a solid return to zero ideal for precision-minded shooters. Dont worry the Xeno Mount System still provides you hard core users the durability youve come to expect from Dead Air. The shorter length and lock-up positioning of the Xeno Mount System make it shine. How exactly? The Xeno Flash Hider doesnt sit deep into the blast chamber. This minimizes focused erosion on your baffles prolonging suppressor life while maximizing sound performance. The shortened length also supports a more future-proof design with a heavy consideration for suppressors with smaller blast chambers across the industry. Plus the Adapter uses the industry standard 1-3/8-24 threads making it not only compatible with our Nomad series but also many other silencers on the market. The Xeno Flash Hider and Adapter mate together with left-handed threads eliminating your worries of the adapter unthreading from your silencer when removed. This also lets you verify your mount is still tight when installing on your firearm. Both the Flash Hider and Adapter feature ample tooling surfaces giving you plenty of room and options. These tool features are accessible even when your suppressor is completely installed. This is for you folks that dont remove your silencer for hundreds or thousands of rounds fired and may need that extra torque. Our material of choice is nitrided 4140 steel for hardness and corrosion resistance. The bonus is that it wont gall your threads as is common with the uncoated 17-4 products out there. Its no fun having your adapter drilled from the back of your suppressor while you're biting your nails hoping it can be salvaged. Nitrided 4140 is just tough. Scouring off carbon and copper deposits is not only easier but youre also less likely to damage your threads. For those desiring a mounting system that offers insane repeatability and durability with very little length or weight added to your firearm the Xeno System is what youre after. All of the features from the large taper the left-hand threads to the accessible tool features provide the optimal platform for precision shooting while still being capable of hard use. The Xeno system takes a simple design and maximizes all the variables in the shooter's favor. Xeno Adapter sold separately.
